The Victorian Government has extended an interim ban on the sale of portable decorative ethanol burners.

An increase in serious injuries reported across Australia prompted Minister for Consumer Affairs Marlene Kairouz to introduce the interim ban in December 2016.

Following the initial ban, Consumer Affairs Victoria inspectors visited more than 300 retailers and removing more than 1,000 decorative burners from sale.

Consumer Affairs Victoria has been working with the Consumer Commission (ACCC) and other state agencies to enforce the ban.

The original 60-day ban has been extended by 30 days to allow the ACCC more time to consider a national ban.

The extension means retailers and online traders must ensure the banned products remain off their shelves and online catalogues.

The maximum fines for selling banned products range from $220,000 for individuals and $1.1 million for corporations.

The interim ban does not apply to ethanol fireplaces that are installed in a fixed position, or those products with a power output of more than 4.5 kW and those used in the heating or warming of food.
